just-template-it

A simple template system.

Installation

npm install just-template-it [--save]

JavaScript usage.

Initialise the Template system:

var templates = require('just-template-it');
templates.init("/path/to/templates", "type");
// Or just:
var templates = require('just-template-it').init("/path/to/templates", "type");

The above code will initialise the system and set the base path to /path/to/templates, it will also set the file type of the templates to .type (the second param is optional, default filetype is jti).
The path and filetype can be changed by using the setTemplatePath(path, type) function.
Observe: setting new path will remove all currently loaded templates.

To fetch a template use the getTemplate function:

templates.getTemplate('nameOfTemplate', {
  "aString": "Some text...",
  "aObj": {"aInt": 5},
  "array": [1,"test",9]
}, function(error, formattedTemplate) {
  if(error) {
    //
  } else {
    //
  }
});

getTemplate takes three arguments:
First is the name of the template, this is without file end, so the nameOfTemplatetemplate in the above example should in the filesystem be at: /path/to/templates/nameOfTemplate.type.
Second parameter is the data object that the template system should replace placeholders with (see further down in readme for more info about placeholders in the template files).
And the third and last parameter is a callback function. The callback takes two args:
First is error, which will only be set if there was an error during run.
Second is the template, formatted and ready withe all placeholders replaced with the data passed in.

The template files.

The template files is quite simple.
They are basically a text file with placeholders (duh), and depending on what data is passed in, the file will replace the placeholders.

Simple example:

Testing {aString}
{aObj.aInt} is a number.
{array[2]} {array[3]}

Using the above js code, this template will be formatted as:

Testing Some text...
5 is a number.
test 9

Just-template-it supports the following placeholders:

• Include (includes another template file): - {include|filename}
• Key-value-pair: "key": "value" - {key}
• Objects: "obj": {"key":"val"} - {obj.key}
• Arrays: "arr": [1,2,3] - {arr[1]}
